LOCKING DEVICE FOR DISPENSING APPARATUS.

Application filed January 10, 1327. Serial No. 160,101.

This invention relates to improvements in locking devices for dispensing apparatus of that class wherein a pump is housed iirthe pedestal of the apparatus, which pump is employed for withdrawing gasoline from an underground reservoir and delivering it into a measuring vessel positioned on the pedestal, and from which vessel the gasoline is subsequently dispensed to the patron ,in quantities regulated by a control mechanism.

he object of the invention is to p'rovlde a device for locking and unlocking a door in the pedestal in'which the pump is contained,

actuated by the control mechanism by which liquid is dispensed from the measure, and to provide also a locking means for the control mechanism, whereby operation of the pump is prevented when the control mechanism is locked. Another object of the improvement is to provide means to prevent unauthorized operation of the filling means for the measuic when the control mechanism for dis pensing liquid from the measure is locked. These objects are accomplished by the construction illustrated in the accompanying drawings, in which I Fig. 1 is a fragmentary front elevation of a dispensing apparatus including that portion of the pedestal thereof containing a pump, and the control mechanism;

Fig.- 2 is a section of a portion of Fig. 1 projected therefrom at right angles thereto;

Fig. 3 is a fragmentary cross sectional view of Fig. 1 on the line 3-3 thereof;

Fig. 4 is a front elevation similar to Fig.7

7 1 with the doors of the pedestal and control mechanism in open position; and

Fig. 5 is a fragmentary cross sectional view projected from Fig. A.

The characters appearing in the description refer to parts shown in the drawings and designated thereon by corresponding characters. I

The invention consists primarily in the means for preventing operation of the pump by which the measuring vessel of the dispensing apparatus is filled, in conjunction with the operating mechanism by which the dispensing of liquid from the measure is controlled. The construction shown consists of a pedestal 1 in which is installed a hand operated pump 2, the pedestal having a hinged door 3 upon the opening of which access is gained to the pump. The pump 2 has a plunger rod 4. provided with a cross head 5, at its outer end, to which is connected an operating lever 6 by whichthe pump is actuated. The lever 6 is so located with respect to the pedestal that whenthe door 3 is open it may be moved to and fro through the door opening 7 in the pedestal.

A bolt 8 projects'from the head end of the pump 2 and has mounted thereon a tilt ing lock member 9 that has engagement with the cross-head 5 when the latter is in its innermost position, there being a lug 9 on said member to obstruct outward movement of said cross-head. The lock member has also anarm 10 provided with an adjustable stud 11 that has engaging relation with-the foot 12 on the bottom of a vertically movable lock-bar 13, which lock-bar is positioned on studs 14 that project from the inner wall of the pedestal 1 adjacent the dooropening.

The door 3 hasnpon its inner face projecting hooks 15 that have locking engage ment with the bar 13 when said door is The measuring vessel, and connections be-- tween the master lever 18 and the vessel by which dispensing operations are controlled, are not herein shown as their particular constructions are immaterial to the present invention, but may be in any known form capable of proper operation by manipulation of the master lever 18.

A reciprocal bar 21 in the control box is actuated'by the master lever 18, and a rockbar 22 in the pedestal is so formed and disposed as to turn upon its pivot 23 in one (tlirection or the other accordingly as themas- -'ter lever is swung inwardly or outwardly upon its pivot 2 1, The lock-member 9 has a crank arm 25 that is connected with the rockbar 22 by a rod 26 so that as the rock-bar is tilted, the lock member 9 is actuated accordingly. Thus, when the master lever 18 is moved to its inward posit-ion, as shown in 41. the lock-member 9 is tilted so as to clear the cross-head 5 on the plunger rod and permit operation of the pumppand also the lock-bar 13 is elevated by engagement of the stud 1.1 on the lockmember with the foot 12 on the lockbar, so that the lockbar is thereby disengaged from the hooks 15 to permit opening Oflll'llG door. The bottom face 5 of the cross-head extends over the lug 9 on the lock-member 9 during operation of the pump, or when the pump handle6 is in any other than its innermost or lockingposition, and the lock-member 9 is thereby prevented from being tilted into locking'position, and consequently the master lever 18, through its connections with said lock member, is prevented from being actuated during operation of the pump, or while the pump handle is in any other than its innermost orlocking position. In this manner simultaneous operati on of the master lever andthe pump is-prevented.

In the operation of the invention, the lid on the control box is first opened, which permits the master lever "18 to be actuated, which lever is thentilted toward'the pedestal, causing the reciprocal bar 21 t-o-tiltthe roek-bar 22. thereby causingthe lock member 9 to move out ofthe path of the cross-head on the pump mechanism so asto .permit operation of the pump. As the lock-member is thus moved. the stud on-thelug l0 of the lockmember bears upwardly against the "foot of the lock-bar. so that saidlock-bar is raised out oi? engagement withthe hooks 15 on the door of the pedestal, :thus permitting the door 3 to beopened. The pumping mechanism is then operated by actuating the pump handle 6. VVhen-the cross-head'ofthe pump is drawn by'thehandle from its:innermost position,it passes over the lug 9' on the lock-member and prevents movement thereof which occordingly prevents movement of themaster lever. In'this manner simultaneous operationof the pump. and the master leveris prevented. By'moving'the pumping; handle'to-its innermost position, as indicated in Fig. .2, thecross-head is accordingly moved beyond the lug 9 on thelockmember, thus permitting the'lock-member'to tilt and the master lever to be freely manipulated, However, when said loch-memberlis tilted to its locking position, the lug 9 obstructs the cross-head preventing operation oi? thepump. Upon 'moven'ient of the door 23 to its closed position the hooks 15 become re-engagcd by theloclt-bar 13, and the door is accordingly locked and access to the pump mechanism is prevented.

closing said opening; acontrol box on the pedestal provided with a lid, a control mech anism for the dispensing apparatus, includinn a master lever tulcrumed in said box and locked against movement by said lid when the lid is closed; a tilting: lock member operable to lock the pump when the operating handle of the pump is in its innermost position and which member is innnovable when said pump handle is in. any other than its innermost position; a lock for said door controlledby said tilting lock member; and. a mechanism actuated by said master lever connected with said lock-member so arranged as to' prevent manipulation of said master lever when said lock-member is out of locking engagement with said pump.

2. In liquid dispensing apparatus having a housing with a door opening; therein; a pump in said housing accessible through said door opening; a lock controlled door for closing said opening; a control mechanism for said dispensing apparatus, including a master lever in supported connection with the housing; a lock member controllmgi the door loclrand operable to lock the pump when the operating handle of the pump is in its innermost position, and which member is immovable when said pump handle is in any other thanits innermost position; and a mechanism c i'mnectin T master lever with said lock memberso arranged that manipulation of said master lever is nevented when said lock-member is out of locked engagement with'said pump.

3. In a liquid dispensing apparatus having; a filling means and a control mechanism, a locking member for said'zfilling means operably connected with said control mechanismyand a member on the filling means that prevents operation of said lock member and the controlmechanism connected there with during'operation of said filling means.

at. 'In liquid dispensing apparatushaving afilling means and a controlmechanism, a locking mechanism related with said filling means and control mechanism, which locking mechanism prevents operation of said control mechanism, during operation of said fillingmeans and which permits operation oi? said control mechanism when said filling means is locked by said locking mechanism.
